The Merrell AllOut Rush brings you a protective yet uninhibited ride on the trails. This shoe features a Uni-Fly midsole, giving you a soft underfoot feel and high mileage cushioning, while a moderate offset design encourages an efficient stride. A lugged outsole maintains traction on technical trails, and a closed mesh upper provides protection from trail debris.

Customer Reviews

Comments: I agree with Simon, the shoefitter deal is off. However, the last is a little bit too curved and too narrow (for me.) They feel (fit wise, not ride wise) like the first version of the New Balance Minimus did. That fact out of the way, Merrell built a really solid winter running shoe-- note that I didn't say trail shoe. The upper is kind of a ripstop nylon material that shelters your foot and feels great in sloppy conditions (I wore it today in 3'' of snow and slop and my feet came out warm and dry.) That same upper though isn't super breathable, which leads me to believe it would be a poor summer trail shoe. The ride is also super firm, which I wasn't expecting with a shoe that has such a big midsole. I kind of wish they lowered it in order to give the shoe more stability. No worries though, most trail shoes are on the firmer side. The outsole is a deal breaker. Its just okay. Its grippy enough for snow, but thats about it. I wouldn't take this on a technical trail or out when there's a lot of loose dirt/ sand/ snow; its just not aggressive enough. It's also stiff as a board; some flex grooves in there wouldn't hurt any. I hope Merrell keeps at it though, the allout rush is very underrated and could be a really solid shoeFrom: Matt, St Paul, MN, USA. November 10th 2014

Premium shoes are for runners who run daily and/or run high-mileage. Premium shoes use high-end materials and the latest technology to enhance comfort.

Standard shoes are for runners who run daily and/or run high-mileage. Standard shoes use time-tested technologies and materials to meet the needs of consistent running.

Performance shoes are for runners who want shoes for faster paced training, such as tempo runs and interval workouts. Performance shoes are also suitable for daily training but will tend to wear faster than Standard and Premium shoes.

Racing shoes are for runners looking for peak performance in racing 5K to marathon distances and beyond. Racing shoes are also suitable for fast-paced interval sessions. Durability is sacrificed to save weight.

Heel-Toe Offset:

?

Heel-Toe Offset

Heel-Toe Offset refers to the height difference between the heel and the forefoot of the shoe. The heel is usually higher than the forefoot but is never lower than the forefoot. Some runners believe a lower offset leads to more efficient running. Traditional running shoes have 10-13mm offsets. Moving from higher to lower heel-toe offsets may require a transition period.

Stack Height:

?

Stack Height

Stack height refers to how much shoe is between your foot and the ground. For this search, stack height refers to how much shoe is under your forefoot, as the heel height will be equal to or greater than the forefoot height.

Barefoot: 1-8mm. The shoe generally does not have a midsole and feels like there is no cushioning. This shoe is all about feeling the ground.

Minimal: 9-13mm. The shoe has a thin midsole but there is a lack of cushioning. Racing shoes and minimalist shoes are common here and there is a feeling of being connected to the road.

Low: 14-18mm. The shoe has a midsole and may have added cushioning technologies. Performance and trail shoes are common here and there is still a good feel for the ground.

Medium: 19-23mm. The shoe has a traditional midsole height. Standard and Premium shoes are common here and cushioning technologies are prevalent. Feeling of the ground varies.

High: 24-29mm. The shoe has a thick midsole and extra cushioning. There is less feel for the ground and more feel of the shoe.

Maximal: 30mm plus. The shoe has an extremely thick midsole and extra cushioning. The focus is on feeling a soft shoe and not really feeling the ground.
